NAME

       xditview - display ditroff output

SYNOPSIS

       xditview [ -toolkitoption ... ] [ -option ... ] [ filename ]

DESCRIPTION

       The  xditview program displays ditroff output on an X display.  It uses no special metrics
       and automatically converts the printer coordinates  into  screen  coordinates;  using  the
       user-specified   screen  resolution,  rather  than  the  actual  resolution  so  that  the
       appropriate fonts can be found.  If ``-'' is given as the filename,  xditview  reads  from
       standard input.  If ``|'' is the first character of filename, xditview forks sh to run the
       rest of the ``file name'' and uses the standard output of that command.

OPTIONS

       Xditview accepts all of the standard  X  Toolkit  command  line  options  along  with  the
       additional options listed below:

       -page page-number
               This  option specifies the page number of the document to be displayed at start up
               time.

       -resolution screen-resolution
               This specifies the desired screen resolution to  use;  fonts  will  be  opened  by
               requesting this resolution field in the XLFD names.

       -noPolyText
               Some  X  servers incorrectly implement PolyText with multiple strings per request.
               This option suppresses the use of this feature in xditview.

       -backingStore backing-store-type
               Redisplay can take up to a second or so; this option causes the server to save the
               window  contents  so  that  when it is scrolled around the viewport, the window is
               painted from contents saved in backing store.  backing-store-type can  be  one  of
               Always, WhenMapped or NotUseful.

       The following standard X Toolkit command line arguments are commonly used with xditview:

       -bg color
               This  option  specifies  the  color  to use for the background of the window.  The
               default is white.

       -bd color
               This option specifies the color to use for the border of the window.  The  default
               is black.

       -bw number
               This option specifies the width in pixels of the border surrounding the window.

       -fg color
               This option specifies the color to use for displaying text.  The default is black.

       -fn font
               This option specifies the font to be used for displaying widget text.  The default
               is fixed.

       -rv     This option indicates that reverse video  should  be  simulated  by  swapping  the
               foreground and background colors.

       -geometry geometry
               This option specifies the preferred size and position of the window.

       -display host:display
               This option specifies the X server to contact.

       -xrm resourcestring
               This option specifies a resource string to be used.

X DEFAULTS

       This program uses a Dvi widget.  It understands all of the core resource names and classes
       as well as:

       width (class Width)
               Specifies the width of the window.

       height (class Height)
               Specifies the height of the window.

       foreground (class Foreground)
               Specifies the default foreground color.

       font (class Font)
               Specifies the font to be used for error messages.

       FontMap (class FontMap)
               To associate the ditroff fonts with appropriate  X  fonts,  this  string  resource
               contains  a  set of new-line separated specifications, each of which consists of a
               ditroff name,  some  white  space  and  an  XLFD  pattern  with  *  characters  in
               appropriate places to allow all sizes to be listed.  The default fontMap is:

               R    -*-times-medium-r-normal--*-*-*-*-*-*-iso8859-1\n\
               I    -*-times-medium-i-normal--*-*-*-*-*-*-iso8859-1\n\

USING XDITVIEW WITH DITROFF

       You  can  use  any  ditroff  output file with xditview, although files which use the fonts
       appropriate to the fontMap will look more  accurate  on  the  screen.   On  servers  which
       support scaled fonts, all requested font sizes will be accurately reflected on the screen;
       for servers which do not support scaled xditview will use the closest font from  the  same
       family.
